Ashton the ant is crawling on the still blade of a ceiling fan when the fan is turned on, causing Ashton to go for a ride. If Ashton sits on the fan blade at a distance of 0.80 m from the center of the fan and turns with a frequency of 1.2 Hz, a) how fast does Ashton spin? b) If Ashton slips off the spinning fan, describe the path he will take.

Which statement correctly describes a step-up transformer? a. it increases the amount of electric energy available. b. it increases the voltage of an electric current. c. it changes direct current into alternating current. d. it has more loops of wire in its primary coil.

How is zig zagging a form of acceleration?

At a certain instant after jumping from the airplane a, a skydiver b is in the position shown and has reached a terminal (constant) speed vb = 52 m/s. the airplane has the same constant speed va = 52 m/s, and after a period of level flight is just beginning to follow the circular path shown of radius ρa = 2330 m. (a) determine the velocity and acceleration of the airplane relative to the skydiver. (b) determine the time rate of change of the speed vr of the airplane and the radius of curvature ρr of its path, both as observed by the nonrotating skydiver.
